One of the most important principles of the circular economy is designing for circularity, which involves products and services being designed with their end-of-life in mind, making it easier to recover and regenerate materials.

DS Smith has developed a series of circular design metrics which give us an accurate picture of the degree of implementation of circular design principles in the production of our packaging solutions and provide quantifiable data to show how circular a given packaging solution is and allow quick identification of the areas of improvement required.

Our Circular Design Metrics measure Supply Chain Optimisation, Recyclability, Planet Safety, Material Utilisation, Renewable Sources, Recycled Content, the Carbon Footprint and Design for Reuse.

* This circularity information was made by using the information of an average single wall box.
